Effects of a CFD-improved dimple stepped-lip piston on thermal efficiency and emissions in a medium-duty diesel engine

International Journal of Engine Research, 2022
Diesel piston-bowl shape is a key design parameter that affects spray-wall interactions and turbulent flow development, and in turn affects the engine’s thermal efficiency and emissions.

Fermentation efficiency of thermally dried kefir

Bioresource Technology, 2008
Three thermal drying methods (conventional, vacuum and convective) were used for drying of kefir biomass and their effect on cell viability, fermentation rate and other kinetic parameters of lactose and whey fermentation were studied. Convective drying rate was higher than conventional and even higher than vacuum at each studied temperature (28, 33 and

SMITE: Using Smart Meters to Infer the Thermal Efficiency of Residential Homes

International Conference on Systems for Energy-Efficient Built Environments, 2020
Residential homes represent approximately 22 % of global energy use and a large proportion of this is due to space heating. The thermal efficiency of a building is typically evaluated manually via surveys, or via intrusive measurements requiring homes to

Maximized Thermal Efficiency Engines

22nd Intersociety Energy Conversion Engineering Conference, 1987
This disclosure provides a method for efficiently converting heat energy to readily usable energy with maximized thermal efficiency. Maximized thermal efficiency is obtained by the use of heat regeneration and working gas processing steps that optimize the heat regeneration, so that any heat that is supplied to the working gas from the external heat ...
